TRACK STRUCTURE.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed. February 4, 1914. Serial No. 818,552.

To all whom it may concern."

Be it known that I, Jeri N. LAMAR, a citizen of the United States, residing at Dannemora, in the county of Clinton and State of New York, have invented certain new and useful Improvements in Track Structures, of which the following is a specification, reference being had to the acconv panying drawings. I

This invention relates to certain improvements in track structures and has relation more particularly to a chair adapted to sup port a rail and to afi'ord a-means whereby such rail may be effectively clamped in operative position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved track structure whereby certain important advantages are attained and thc device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, allas will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein-- Figure 1. is a view in top plan of a track structure constructed in accordance with an embodiment of my invention; Fig. 2 is a view in side elevation of the device as illus trated in Fig. l, with the coacting rail shown in section; Fig. 3 is a sectional view taken substantially on the line 3 3 of Fig. 1; Fig. 4 is a sectional view taken substantialiv on the line l--et of Fig. 2; and Fig. 5 is a view in elevation, detached, of one Form of clamping member herein included, the coacting rail being indicated by dotted lines.

Asmliscloscd in the utcoun'ianying drawings, i denotes a tie which may be of wood or iron as best serves the necessities oi prac -'co and on the opposite extremities of which are adapted to be rested achair, in (licatcd as a whole by A, such chair being provided at its opposite longitudinal sides at si'lbstani ally the center thereof with the dcpcmlinp; .ips or flanges adapted tooverlie the adjacent portions of the tie and serve as a means for maintaining the same in operative ioeaticm. .l also provide the vertically disposed openings 3 through the chair A through which suitable bolts it or the like are adapted to pass, such bolts being also directed through the tie 1 whereby such chair may be efl'cctively clamped to the tie, it being understood that enacting with such bolts 4 are the conventional nuts or burs 5.

The intermediate portion of the chair A recess 6, in which is adapted to be received the base portion 7 of a rail B, while the ad- ;acent marginal. portions 8 of the chair are provided with the longitudinally directed .slots or channels 9 disposed in offset relation and of a predetermined width and be ing provided with the alined elongated slots or openings through which are adapted to be extended the clamping members 10, herein shown-as conventional bolts and their coacting nuts 01 burs which are adapted to enact with the clamping members 11 and 12 disposed in the opposed grooves or channels 14. As herein disclosed, the clan1ping members 11 and 12 are of substantially the same width as the channels or grooves 9 and are adapted to be moved l0ngitudi- .nally thereof so that the engaging faces 15 thereof may be caused to properly engage with the rail B. Intermediate their length, such clamping members 11 and 12am pro vided with elongated slots through which the retaining means 10, hereinbeforo referred to, are adapted to project, the elongated slots or openings readily permitting such movement of the clamping members 11 and 19 as the necessities of practice may require.

As herein disclosed, the proper engagement of the clamping members 11 and 12 with the rail is effected through the medium of the elongated members 16 disposed in the recesses or grooves 17 arranged lengthwise of the chair A across the base of the grooves or channels 9 and across the recess 6 and in disposed through the marginal portions 8, such bolts having relatively opposed ends provided with upstanding projections adapted to engage the lower outer ends of the clamping members 11 and 12 so that endwisc movement imparted to the elongated members 16 will result in the requisite engagement of the clamping members 11 and 12 with the rail. The members 16 are of such a length as to project beyond the outer end of t e openings 18, such projected portions 19 ar adapted to be engaged by the retaining or clamping nuts or burs 20 is provided with the transverse pocket or communication with a suitable opening 18.

whereby it will be seen that the clamping men'lbers i1 and 12 are effectively maintained in proper engagement with the rail.

In order to provide a means whereby the rail B may be effectively maintained against turning, l. find it of advantage to "form the clamping member 12 with the upstanding extension 21 adapted to bear against the head or wall 22 of the rail and which thought. to operate in a. manner which is clearly obvious to those skilled in the art to which my present invention appertains.

From the foregoing, it is thought to be obvious that a track structure constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapt-ed tor use by reason of the convenience and facility with which the rails may be applied thereto and the security with which such rails are maintained in operative position and it will also be obvious that my in vention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my innication with suitable openings disposed in the adjacent portions of the end margins of the chair, elongated members disposed through such openings and resting in the longitudinally directed recesses, such mcmhers being adapted to operatively engage the clamping members, and means eoacting with such elongated members for maintaining the clamping members in proper engagement with the rail. I

Q. A rail chair having a transverse recess adapted to accommodate the base of a. rail, the end marginal portions of such chair be ing provided with longitudinally disposed channels in communication with the trans verse recess, clamping members slidably po sitioned within the channels, each of such channels and the transverse recess being provided with a longitudinally disposed chan nel, elongated members resting in the longitudinally directed recesses, such members being adapted to operatively engage the clamping members, and means coacting with such elongated members for maintaining the clamping members in their proper engagement with the rail 3. A rail chair having a transverse recess adapted to accommodate the base of a rail, the end marginal portions of such chair being priwided with longitudinally disposed channels in communication with the transverse recess, clamping members slidably positioned within the channels, each of such channels and the transverse recess being pro vided with a longitudinally disposed channel, elongated members resting in the longitudinally directed recesses,- such members being adapted to operatively engage the clamping members, means coacting with such elongated members for maintaining the clamping members in their proper engage ment with the rail, and additional retaining means for the clamping members coacting with such clamping members and the chair, such means permitting a limited movement of the clamping members. I

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
